A talk is given by

     Department of Computer Science
     Leipzig University.

and is entitled

     "Predominance Tag Maps"

Abstract:

     A predominance map expresses the predominant data category for each
     geographical entity and colors are used to differentiate a small number of
     data categories. In tag maps, many data categories are present in the form
     of different tags, but related tag map approaches do not account for
     predominance, as tags are either displaced from their respective
     geographical locations or visual clutter occurs. We propose  
predominance tag
     maps, a layout algorithm that accounts for predominance for arbitrary
     aggregation granularities. The algorithm is able to utilize the font sizes
     of the tags as visual variable and it is further configurable to implement
     aggregation strategies beyond visualizing predominance. We  
introduce various
     measures to evaluate numerically the qualitative aspects of tag maps
     regarding local predominance, global features, and layout stability and we
     comparatively analyze our method to the tag map approach by Thom et al. on
     the basis of real world data sets.

On behalf of Professor Scheuermann all those interested are cordially  
invited to attend.
